I was introduced to the calculations from the class since I recognized numerals. As my standards levelled up, I was taught to calculate arithmetic problems. I started studying in higher standards and suddenly trigonometric equations showed up feelings.
One day in my class, the instructor recommended I buy a calculator that could handle certain equations like simultaneous, quadratic, and polynomial degree equations. I had no idea which calculator to buy and where would I get them.
I went to the market and searched for scientific calculators in every shop. Finally, I found a stationery shop for it. I asked the shopkeeper to show me some of the scientific calculators that would fit the requirements of my standard.
He asked me my standard. I answered Bachelors in Engineering. He brought some of the best suitable scientific calculators for me to choose from. He explained the functions of that calculator. I bought the top best and returned home.Â
To save your time and not to get problems searching for a calculator, I have hand-picked the top 8 best scientific calculators for you to buy in 2020. Here goes the list.
